[Solved] Motherboard Won't Power ON - No POST

Go to solution Solved by zanthros,

Remove the power cable, remove the CMOS battery and push and hold the CMOS button for 10 seconds.... (Cmos button is by the power button on your board and labeled CMOS)

Hello,

 

My motherboard doesn't seem to power on at all. I was cleaning my computer up and plugged everything back in before closing the whole case up, I checked if the computer booted and everything was working fine, it all came on and booted to windows. I then popped one of the side panels on and moved my PC to the area it normally sits, I then plugged all the USB's like mouse, keyboard, etc. then once I finished this I plugged the power cable in and flicked the button on the power supply, my computer then lit up for a split second (I hadn't turned the computer by this time, the motherboard lights up when it is receiving power). After this I thought it was strange and tried to turn it on via the power button on my case, no luck.. So my question is what is wrong? And what can I do to fix it?

 

I've so far tested the power supply checking it turned on and work which it does. I've since not tested anything else other than only plugging in the main power sources the board needs.

 

(Computer is currently sitting on a box with only the cooler and power plugged in and still won't power on)

Recheck the plug at the wall plug and at the back of the PSU.

I've checked all of this, I've even tested the power supply on another computer and it worked.

Unplug all devices and re-check. Make sure that all MB power connections are plugged in firmly.

Is the power switch cable on the correct posts?

I don't see anything hooked up to the power on pins on the left side in the picture. (By the buzzer/speaker). Are you manually jumping the pins?

The motherboard as a power button on it, I've also tried manually jumping it.

Is it possible I've short circuited the motherboard?

Ok, If you have verified that all of the memory is in place properly, there is nothing plugged in improperly, all connections are clean and tight, there are no bent/damaged pins on anything, none of the components are damaged (electrically speaking) then the only other thing that I can think of is that the motherboard became damaged when you plugged in the power supply or it got damaged in the process of cleaning. ESD (electro static discharge.... static electricity)  can damage a motherboard easily. just for laughs I would try to clear the cmos and see if it boots...

I've never cleared a cmos before.. Haha, how do I do it?

Thanks... glad it worked out for you. I have only had this work on one "dead board"  before but figured it was worth a try. :)

I had to create an account on this forum, just to thank you for this awesome help. It worked for me too!

I was already looking for a new motherboard for replacing the dead one. But, I was afraid it could be something else, so I double checked the support pages to find a solution. And I got it! Great!

Also signed up to say thanks! Have an elderly customer with a GA-H110M-M.2 board that wouldn't boot, this solution worked! No button on the board, but closing the clear cmos jumper did the trick. Thanks again!!!

This doesn't work for me. Tried it but it still won't power on. I have an ASUS A8N-E and I'm using an Athlon 64 3700+ San Diego. The LED on the Mainboard is lit up but jumping the power pins doesn't do anything 😞

I am having this same problem, mobo lights up for a spare second, then nothing happens. Did you perhaps managed to fix your problem?
